Different color eyes, Liv’s chin is more pointed and Michelle’s nose is wider, but these two could pass for sisters. Is Michelle sure of her parentage? Because Steven Tyler DID get around back in the ’70′s. I’m just sayin’.

So Liv and Michelle were both at film screenings on Monday night. Liv showed up at an “Iron Man” screening at the Tribeca Film Festival and Michelle was at the premiere of her upcoming movie, “Made of Honor.” That’s the Patrick Dempsey “My Best Friend’s Wedding” redux with McDreamy in the Julia Roberts role. I hated that movie on basic principles and this one doesn’t look any better, but how come I find myself wanting to see it? I certainly have better things to do with my money, let alone my time, and yet….

No, must resist. I’ll end up annoyed and irritated by everyone in the theater who laughs at the stale jokes.

Who am I kidding? I’ll get sucked in. I hate you, Hollywood.
